Structural features and the cutting properties of boron nitride-base superhard materials

Study of quenched steels machining with a polycrystalline Hexanite-R cutting tool

“…It can be observed that the Hexanite-R tool shows a lifetime five times higher than the hardmetal one for a much smaller wear standard. Hexanite-R showed a lifetime 30% higher than the Amborite one [13,14], for a wear rate 10% smaller.…”
